In order topermit the economical installation of a heating system Whieh is particularly ad ptel for lowepriced dwellings or other lgauilding` `Ipovide in saidflor'a' Channel. rigigrins die. e the exterior walls lo'fwth'e building and preferably at distance of approximately one foot from said walls, since I have found, by exhaustive tests and research, that such a distance permits the most eicient operation of my novel heating system.

In the form shown, a suitable heating element, in the form of a radiator of conventional form, consists of a pipe lll having a plurality of radiating fins Il thereon. The said radiator is suiti @anni ne building; in susa a: manhattan it may te retainer; in, resided iii-initiated iii Fiss: i ali eredi!

"'Exhaustie tests and reseach"o'ziducted on my invention have further proven that the heating efficiency of the radiator will become less as the said radiator is placed away from the wall I3 toward the opposite wall l5 of the channel 9. For instance, the ltests have proven that, when the radiator is placed in the center of 55 the channel, as shown in Fig. 4, a heating eli- 3 ciency of 74% of the standard output of the particular radiator used is obtained. Also, when the said radiator is placed adjacent the opposite wall l5, as shown in Fig. 5, an ecie'ncy of 64% of the standard output of the particular radiator ,used is obtained. I have therefore established the correct position in which the radiator is to be placed within the groove 9 for rendering my invention operable for the highest degree of efliciency; the said position being illustrated in Figs. 1 to 3 in which position the flowV of air through the radiator, as illustrated in Fig. 3, may be controlled by the use of a suitable damper, such as at I4, for selectively controlling the flow of the air through the radiator so that it will be heated to any desired degree between the 39% heating capacity, when the damper is closed, as shown in Fig. 2, and the 85% heating capacity, when the damper is open, as shown in Fig. 3.

It will be clearly understood from the above description that my improved heating system may be installed in a building by extending a single pipe along the outer walls of the building and through the adjoining rooms therein, which may be separated by suitable partitions, as indicated at l1, and that, by providing a separate damper in each room, the system may be adjusted for different degrees of heating in each room, independently of the adjoining rooms, by simply adjusting the damper I4 in the particular room or rooms wherein such adjustment is desired.

While no means has been shown in the drawings for adjusting the damper to different positions between the open and closed positions, the same may be readily provided by such as a chain and aY suitable hook arrangement for receiving different links of the chain to regulate the position of the damper. Other forms of fastening means for the damper may be provided, if desired, and such may comprise a suitable arrange- Yment by which the damper may be frictionally held in any adjusted position.

As illustrated in Fig` 1, a suitable grill I6 may be used to cover the heating system. This grill may be positioned flush with the floor in a suitable recess providing supporting shoulders for the grill along the edges of the channel 9 as clearly illustrated.

I claim;

1. For a building, a heating system of the character described comprising a heating radiator in the form of a pipe located within a channel below the plane of the floor of said building and running along and parallel with the walls thereof, the said pipe running adjacent said channel at one side thereof and along the wall of the channel nearest to the Wall of the building, and means between said radiator and the wall of said channel spaced farthest from thev radiator and substantially at floor level for controlling the ow of air relatively to the radiator as it moves along the floor toward the walls of said building and said channel being spaced a sufficient distance from the building wall whereby heated air may travel horizontally for a limited distance before contacting the building wall.

2. For a building, a heating system of the character described including a formation in the iloor of said building providing a channel in said floor running along and adjacent to the outer walls of the building, a heating element in the form of a radiator located Within said channel below the plane of said floor and running along and adjacent to the wall of said channel nearest to the walls of the building, the said radiator being spaced from the bottom of said channel and from the wall thereof farthest from the walls of the building, and means between the said radiator and the said farthest Wall at substantially floor level for controlling the ow of air relatively to said radiator as it moves along said floor toward the said outer walls of the building.

3. For a building, a heating system comprising a radiator in the form of a pipe having a plurality of radiating fins thereon and located within a channel in the floor of said building and running along and adjacent to the outer walls of the building, the said radiator being supported adjacent to the wall of said channel nearest to the said walls of the building and above the bottom of the channel, a damper hingedly mounted upon the opposite wall of said channel adjacent its upper end and adjustable between said radiator and said opposite wall for controlling the degree to which air moving along said floor toward the outer walls of the building is permitted to dip into said channel and move through the fins of the radiator to thereby control the degree to which the said air is heated by the system.

4. For a building having a plurality of rooms, a heating system comprising a formation in the oor of said building providing a channel running continuously through separate rooms in said building and adjacent to an outer wall thereof, a heating element in the form of a radiator located wthin and running along said channel below the plane of the floor and adjacent to the wall of the channel nearest the building wall, and a separate damper in each of said separate rooms between the said radiator and the opposite wall of the channel and at substantially oor level for independently regulating the degree of heating in each room by controlling the flow of air entering the channels as it moves along the floor toward the said outer wall of the building in said room.
